We have started a new project and decided to use Analog Devices digital isolators instead of opto-couplers. But we have some doubts. I have a few technical questions concerning ADUM1400 digital isolator.
I want to use the ADUM1400 device with 5V / 3,3V supply. To protect the device from too high input voltages, we wonder if the ADUM1400 (and other ADUM's) has internal clamping diodes for this purpose ?
